PURPOSE:To enable delay and advance conditions for a schedule while actually executing drive by calculating drive information periodically based on input information and measured time by a time-measuring means and by displaying it on a screen occasionally. CONSTITUTION:An liquid crystal display TV device is provided with four opera tion modes, namely 'TV', 'Measure', 'Map', and 'Navigation'. In the 'TV' mode, normal television broadcasting is received. In the 'Measure' mode, actu ally measured value of a length is displayed on a display part 53 by tracing an object to be scanned by a scanning roller 61 of a remote controller 51. In the 'Map' mode, an object map is traced by the scanning roller 61 of the re mote controller 51. By selecting a scaling value of the map, a distance is calcu lated and is displayed on the display 53. In the 'Navigation' mode, a schedule distance and either one of schedule speed and schedule time are input and time until arrival or an average time until arrival is displayed. |
